Sample Preparation for DNA Sequencing
General Information
The MBRS aims for a turnaround time of 24 hours or less for the sequencing samples. Much of our cycle sequencing process is automated and the speed at which we can cycle, load, and run samples is dependent on how the samples are presented to us. We try to work within constraints of the computer systems and our robotic liquid handling system. File names, sample size, and quality are important. If we have to work with individual samples that do not conform, it takes longer for us to do the sequencing. All samples we receive by 10:30 AM will be processed that day and with some of that data being posted before 5:00 PM. However we process samples whenever we have a sufficient numbers to fill a run (48). Thus it is best to deliver your samples as soon as they are ready. It is not uncommon for us to start processing samples as early as 6:00 AM or as late as 4:30 PM. The faster samples get delivered to us the faster we get the results back.
Template and Primer
As noted MBSR prefers to perform the sequencing chemistry for you. Prepare your samples in the following manner: combine each sample template and its primer in a single 1.5 ml mircocentrafuge tube in the concentrations as indicated in the information below. Final sample volume should be 20 microliters. If they are not 20 ul in volume , add Milli-Q water to bring them to volume.Primer

Delivering samples to the Molecular Biology Shared Resource Lab.
Bring a copy of your order form with your sample(s). They can be dropped off 24/7 in refrigerators located in the laboratory of 241 Remsen, or the Borwell loading dock (next to the Rubin elevator).
Submitting samples in a 96 well-plate
We do offer reduced pricing for samples submitted in a 96 well-plate for sequencing. The set up for the samples is different than described above so please contact the Core and allow us to assist you.
